Improvement in base heating-stoves



UNITED STATES PATEET EEICEo VALENTINE VERMILYE, OF SANDWICH, ILLINOIS.

IMPROVEMENT IN BASE HEATING-STOVES-- Specification forming part of Letters Patent No. 157,249, dated November 24, 1874; application filed October 21,1874.

' I do hereby declare that in the same is contained a full, clear, and exact description of my said invention, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention relates to means by which the heated gases and other products of combustion are utilized after leaving` the stove proper by being conveyed from the hot-air base of the stove through a pipe which makes the circuit of the base of the stove at the under side thereof, and passes through an opening or thimble in the hot-air base and upward to a hot-air chamber in communication with the direct draft of the stove and with the smoke-pipe through Whichthe said gases and products of combusf tion escape to the chimney.

In the accompanying drawing forming a part of this specification, Figure l is a plan, partly in section, of a base heating-stove embodying my improvements. Figs. 2 and 3 are, respectively, vertical sections of my invention upon the lines fv w and :v y.

Similar letters of referenceindicate similar parts in all the views.

A is the fire-pot and B the casing or cylinder of the stove. The cylinder is considerably larger in diameter than the re-pot, thereby forming around the fire-pot the space c, which connects the interior of the same with the base C.' D is the aforesaid pipe or conductor of the products of combustion, commencing at the under side of the base C, to which it is attached, and extends around and under the same. to a point at the back of the stove, where it passes through the base and extends upwardly to the hot-air chamber E. rIhe base C is provided with a thimble, O', at the point where the pipe D passes through it, to prevent any escape of gas from the base O, and to obviate the necessity of a close joint being made between the pipe D and the base C. Fis an opening in the cylinder B, and forms the means of communication between the space a and the chamber E. G is a hinged damper, adapted to rest, when in a horizontal position, upon a partition, b, in the hot-air chamber, and close an aperture, c, therein. When the damper is in this position the direct draft, by means of the opening F and aperture c, is cut off and the entire products of combustion compelled to take the more circuitous passage through. the base C, pipe D, and hot-air chamber E, thus heating a radiating-surface near the floor.

The object in extending the pipe D through the base O, as before described, is to reheat the gases in the said pipe as they ascend to the chamber, to increase their velocity, and consequently the draft in the smoke-pipe and chimney.

In addition to the advantages derived from the heating ofthe pipe D by gases that, under other circumstances, would pass unutilized to the chimney, the efficiency of the stove is increased in the following manner: Heating-colupartments d are formed at the sides of the base O, from the bottom of which compartments extend the pipes e, which lead to the outer air. rlhe apartment is thus supplied with fresh air heated by being brought into contact with the sides of the base and delivered through the openings f.

Stoves embodying my improvements may be ornamented in the usual way, and a very pleasing effect produced by inclosing the pipe D within a contigurated casing of open or grated work, which in some cases may extend to the floor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

In a base heating-stove, the pipe D, as described, adapted to convey the heated gases from the base O to a point below the said base, Y

and thence, through the same, to the smokepipe, in combination with thimble O', the heating-chamber E, and damper Gr, substantially as set forth.

In testimony whereof` I have hereunto subscribed my name this 17th day of October, A. D. 1874.

VALENTINE VERMILYE.
